BESERVE-FUEL-SUPPLY TANK.

Application filed May 9, 1525. Serial No. 29,131.

To all whom it may concern:

Be it known that I, EDGAR A. BOND, a citizen of the United States, residing at Ramah, in the county of McKinley and State of New Mexico, have invented certain new and useful Improvements in a Reserve- Fuel-Supply Tank, of which the following is a specification.

This invention relates to improvements in fuel feeding devices for automobiles, and has for its principal object to provide a reserve supply for use in case of an emergency when the fuel in the main tank has been entirely consumed.

One of the important objects of the present invention is to provide a reserve supply tank which communicates with the main supply tank, the former being filled simultaneously with the filling of the main tank, means being provided whereby the fuel in the main tank will be entirely consumed before fuel in the reserve or auxiliary supply tank can be obtained.

A further object is to provide a reserve supply tank which includes a fitting, the latter havin comunication with the carburetor of t e internal combustion engine of the automobile, means being further provided whereby the fitting communicates with the main tank, an additional means being provided whereby the fuel in the auxiliary or reserve tank may be discharged therefrom through said tank into the supply pipe extending to the carburetor.

A further object is to provide a device of the above mentioned character which is simple in construction, inexpensive, strong and durable, and further well adapted to the purpose for which it is designed.

Other ob'ects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this application, and in which like numerals designate like parts throughout the same:

Figure 1 is a sectional view through the auxiliary tank and the fitting associated therewith showing the relation thereof with reference to the bottom of a main fuel supply tank, and

Figure 2 is an end elevation of the auxiliary tank and the fitting.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the bottom portion of a fuel tank such as is commonly provided on automobiles and for the purposes of the present invention, I designate the same as a main fuel supply tank. Disposed below the main fuel supply tank is the reserve or auxiliary supply tank. 2. Communication between the aforementioned tanks is afforded through the medium of the short piece of pipe 3, the upper end of which is threaded into an internally threaded flange 4 which extends around the opening 5 provided in the bottom of the main tank. The lower end of the pipe 3 is also threaded in a similar internally threaded flange 6 which is disposed around the opening 7 formed in the top of the reserve or auxiliary tank 2. This construction is more clearly illustrated in Figure 1.

An opening 8 is formed in the bottom of the auxiliary or reserve tank 2 in registry with the opening 7 and an internally threaded flange 9 surrounds the opening 8, and is disposed on the bottom of the auxiliary tank. A fitting designated generally by the numeral 10 has its upper end externally threaded, and threaded into the internally threaded flange 9 whereby the same depends from and is supported by the auxiliary or reserve fuel supply tank 2. The fitting is provided with a chamber 11in the lower portion thereof. A fuel discharge pipe 12 extends from the side of the fitting 10, and communicates with the upper portion of the chamber 11 by the coupling 13. The pipe 12 is adapted to extend to the carburetor of the automobile, not shown, in the usual manner.

The fitting 10 is further provided with the vertical passages 14 and 15 respectively, the same affording a communication between the auxiliary tank 2, and the chamber 11. The upper portion of the fitting is further provided with a transversely extending conical bore 16 in which is seated the rotary valve 17 the latter being also substantially conical shaped. The valve 17 is provided with the transversely extending passages 18 and 19 respectively, the same being disposed in right angles with respect to each other, and the purpose thereof will hereinafter be more fully described. A suitable handle 20 is associated with the rotary valve for facilitating the actuation thereof.

A short piece of tubing 21 has its lower end externally threaded and threaded into the upper of the vertical passage 14." This short piece of tubing extends upwardly within the auxiliary tank 2, and the upper end thereof extends into'the lower end" of the short piece of pipe 3, as is clearly il lustrated in Figure 1 of the'drawing, and the purpose of this arrangement will also hereinafter be more fully described.

A pet cock 22 is provided at the bottom of the fitting 10, and has communication with the chamber 11 for the purposes of the chamber to be drained and the sediment removed therefrom whenever it becomes necessary.

Normally, when the parts are arranged as shown in Figure 1 of. the drawing, it is obvious that when the main fueltank 1 is filled, the auxiliary tank will also be simultaneously filled. With the valve .17 disposed in the manner as illustrated'whereby the port or passage 18 isin communication with the passage 14 and the part 19 is out of communication with the passage 15, fuel from the main tank 1 will beadapted to flow into the chamber 11 and out through the discharge pipe 12 to the carburetor for the usual consumption by the engine. .The short piece of tubing 21 affords a means whereby the .fuel from the main tank will be delivered to the chamber 11 of the fitting 10;

\Vhen the main supply tank 1 becomes empty, and there is no possibilityof any fuel entering the chamber 11 through the short piece of tubing 21, and the passage 14 of the fitting. when the port 18 of the valve 17 is in registry therewith, the valve is rotated. by actuating the handle 20 so that the port 18 'i sbrought 'outof alignment or registry with-thepassage l land simultaneously causing theport of the valve 17 to be in alignment or registry with the passage 15. hen the parts are arranged as thus described, the fuel in the reserve or auxiliary supply tank Qwill be discharged therefrom into the chamber 11 and enable the automobile to be operated so that operator may reach the filling station which is located thereby in order that the main fuel supply tank may be refilled. It is of course to be understood that the auxiliary tank will only hold about one gallon gas which is sufficient enough to permit the further operation of an automobile in case of an emergency, the fuel in the main supply tank having been entirely consumed.

It will thus be seen from the foregoing. description, that a fuel feeding device has been provided which will at all times be positive and efficient in carrying out the purposes for which it is designed, and the simplicity in which the present device is constructed enables thesameto be readily and. easily attachedto fuel supply tanks now 7 provided on automobilesofvari'ous makes.

I vided.- with a. fuel chamber, a discharge pipe extending therefrom, ,said fitting, being provided with'a pair of passages communicating at their lower ends withthe chamber, one. of said passages communicating at its upper, end withv the 'mainjfiiel supply tank, the other. ssage. c mmunicating. at its upper end with the reservesu ply) tank, and means associated with the tting and said passages for effectingthe exc'om'muni- I cation of one of the passages with said chamber.
